My technicians can only see what it assigned to them on their home page, but they have the ability to press the Advanced Search box and search by all different criteria and see tickets that.

1) are not assigned to them and / or are assigned to other employees.

2) that have not been approved yet based on the flow process.

I would like to see the ability to disable the advanced search under the technician role, or a more limited technician role be created that prevents the technician from seeing any type of ticket that is not assigned to them yet.
